H'g/J Current Amplfiers

Parasounds High Current Amplifiers offer explosive power with uncompromised sound quality. Our focus on
a high current/high bias design influenced by John Curl, utilizes complimentary discrete circuitry to assure every
watt is crystal clear and available for crisp vocals, magnificent explosions, and dynamic music. Each amplifier features
l2 volt DC triggers, gain controls, and bullet-proof protection for ease of use and peace of mind. Give us the most

demanding music or the most action packed soundtrack, and you will love what you hear.
